When I run wine, the sound played in games stutter and effects are played with delays. If I try to play with aplay, sometimes I get underruns like: underrun!!!

I have it only in Czech from logs: alsa-sink.c: ALSA nás probudila z důvodu zápisu nových dat na zařízení, ale ve skutečnosti nebylo co zapisovat. alsa-sink.c: S největší pravděpodobností se jedná o chybu v ovladači ALSA "snd_hda_intel". Nahlaste prosím tento problém vývojářům ALSA. alsa-sink.c: Probudilo nás nastavení POLLOUT - nicméně následné snd_pcm_avail() vrátilo 0 či jinou hodnotu < min_avail. ratelimit.c: 60 events suppressed ratelimit.c: 30 events suppressed This was 3 seconds after "IRQ timing workaround" was activated above. Then there are hundreds of "events suppressed" All the other information are hopefully in alsa-info: http://www.alsa-project.org/db/?f=2b8f40d47bc5a0ba3499ab5fdf2d8aa8ebe980f8 Note that there is PA: Running - No, but the info was probably taken while the PA process was not alive. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
